About
The person behind the architecture
I'm Radwan — a father of two girls, a tech enthusiast, and someone who genuinely loves solving hard problems. Based in Copenhagen, I work with businesses across Europe and beyond to build the kind of digital infrastructure that doesn't just work today, but scales with you for years.
With over 8 years of hands-on experience spanning enterprise systems, microservice architecture, and e-commerce platforms, I bring a rare combination: deep technical expertise and an entrepreneurial mindset.
Outside of work, you'll find me following sports, exploring ideas through books, and always looking for the next interesting conversation.

What I help you build
Every engagement starts with understanding your business reality — not just your tech stack.
01
Enterprise Integration Architecture
Your systems don't talk to each other — causing data silos, manual workarounds, and bottlenecks that slow down your business.
You walk away with
A scalable, documented integration layer that connects all your business-critical systems — clean, maintainable, and built to last.
Start a conversation02
E-commerce Development & Optimisation
Your digital sales channels are fragile, hard to manage, or simply don't convert — costing you revenue every single day.
You walk away with
A powerful, fast, user-friendly commerce system that performs — and that your team can actually run without a constant firefight.
Start a conversation03
Technical Consulting
You can't find reliable, affordable consultancy that understands both the technical complexity and the business reality.
You walk away with
Clear direction. No fluff. A plan you can execute — whether with me or your own team.

EV Charging Infrastructure

Lead Architect & Hands-on Developer

MicroservicesAzureCRMMulti-channel
The Challenge
Clever's systems were unstable and deeply entangled — multiple teams integrating directly with the same third-party systems, a cloud infrastructure hitting its limits, and a monolithic architecture that couldn't keep up with the pace of the business.
Outcomes
Scaled from 1 to 7+ active sales channels
Centralised 3rd-party integrations via a single proxy service layer
Full control over the onboarding flow — end to end
Dramatically improved system observability and fault tracing

CMS MigrationOptimizelyContent Platform
The Challenge
Aller Media — publishers of some of Scandinavia's most-read magazines and digital properties — were constrained by an ageing Umbraco CMS that couldn't support their content velocity or multi-brand digital ambitions.
Outcomes
Successful migration to Optimizely CMS across multiple brands
Enabled editorial teams to move significantly faster
Foundation set for multi-brand digital expansion
Zero critical data loss across the migration

Industrial Distribution
B2B Commerce Platform
Built a multi-tenant B2B commerce platform integrated with SAP ERP
Lead Full-stack Developer & Architect
9 months
B2B E-commerceERP IntegrationMulti-tenant
The Challenge
A mid-sized industrial distributor was processing thousands of B2B orders manually via email and phone. Their fragmented systems couldn't handle custom pricing, bulk ordering, or the approval workflows their enterprise clients required.
Outcomes
Reduced order processing time from 3 days to under 4 hours
Onboarded 40+ enterprise accounts within the first quarter post-launch
Custom pricing and approval workflows eliminated 90% of manual steps
Self-service portal reduced inbound support tickets by 60%

Influencer & Content Creator Economy

ShopifyD2CAutomation
The Challenge
A group of content creators and social media influencers had large audiences but no reliable way to monetise them through their own channels. They were losing revenue to third-party platforms with high commissions and no brand control.
Outcomes
Launched 5+ branded Shopify stores across different niches
Implemented automated email flows converting at 4–8% per campaign
Integrated social commerce channels — reducing dependency on platforms
Combined store revenue exceeded expectations within 60 days of launch
